Dispersant (Dispersant) yog ib qho kev cuam tshuam tus neeg sawv cev nrog ob yam khoom sib txawv, ob qho tib si lipophilic thiab hydrophilic.Cov khoom thiab cov khoom ua kua uas nyuaj rau yaj hauv cov kua, tuaj yeem tiv thaiv kev sib haum xeeb thiab condensation ntawm cov khoom thiab tsim cov amphiphilic reagent xav tau rau qhov kev ncua ruaj khov.

Lub luag haujlwm ntawm dispersant yog siv wetting dispersant kom txo tau lub sij hawm thiab lub zog xav tau los ua kom tiav cov txheej txheem dispersion, stabilize lub dispersed pigment dispersion, hloov cov khoom nto ntawm cov xim pigment, thiab kho cov lus tsa suab ntawm cov xim xim.Nws yog embodied nyob rau hauv cov nram qab no yam:

1. txhim kho cov luster, ua kom cov nyhuv ntawm leveling luster ua tau qhov tseem ceeb tshaj plaws yog nyob ntawm txheej txheej ntawm lub teeb tawg (uas yog, qee qhov flatness tuaj yeem ua tau., Tau kawg, yuav tsum txiav txim siab seb puas txaus, tsis yog xav txog qhov tus naj npawb ntawm cov khoom ib txwm muaj, cov duab, thiab xav txog lawv cov kev sib xyaw ua ke), thaum qhov loj me me dua qhov teeb meem teeb meem (tus nqi no tsis paub tseeb), kev ua haujlwm rau lub teeb pom kev zoo, luster yuav tsis txhim kho, tib lub npog quab yuam cia siab rau kev tawg ua rau lub ntsiab npog. quab yuam yuav tsis nce (tshwj tsis yog cov pa roj carbon dub feem ntau los ntawm kev nqus lub teeb, organic pigment tsis nco qab).Nco tseg: qhov teeb meem tshwm sim yog hais txog qhov ntau ntawm cov teeb pom kev tsis zoo;tab sis nco ntsoov tias qhov txo qis ntawm cov khoom qub yog txo cov viscosity ntawm cov qauv, tab sis qhov nce ntawm qhov saum npoo yuav txo tau cov dawb resin, seb puas muaj qhov sib npaug, tab sis cov hmoov txheej txheej tsis yog qhov thinner zoo dua. .

2. tiv thaiv ntab xim plaub hau paj.

3. txhim kho cov xim quab yuam kom them sai sai rau cov xim quab yuam hauv cov xim tsis siv neeg hloov xim tsis yog qhov siab dua.

4. Txo cov viscosity thiab nce cov xim xim.

5. txo flocculation yog zoo li no, tab sis lub thinner particle nto zog, qhov siab dua, qhov siab dua lub zog adsorption ntawm dispersant, tab sis lub zog adsorption ntawm dispersant yuav ua rau tsis zoo rau kev ua tau zoo ntawm cov zaj duab xis txheej.

6. Yog vim li cas rau kev ruaj ntseg cia zoo ib yam.Thaum lub zog ruaj khov tsis txaus, qhov kev ruaj ntseg cia yuav phem dua (ntawm koj daim duab).

7. nce xim zaub, nce xim saturation, nce pob tshab (organic pigment) los yog npog quab yuam (inorganic pigment).

HD605 wetting dispersant pab kom moisten thiab stabilize cov xim, tiv thaiv cov xim ntab thiab xim xim, tswj cov xim ruaj khov npog lub zog thiab xim lub zog thaum khaws cia, thaum ua kom cov xim ntau tshaj plaws thiab kev sib tsoo tsawg kawg nkaus.Vim tias cov additives no tuaj yeem txo cov viscosity thiab nce mus rau qhov siab tshaj plaws ntawm cov xim thaum dispersed, cov txheej thiab cov xim concentrate slurry uas ua tau zoo dua.HD605 raug pom zoo rau kev tsim cov pigments hauv dej.Rau corrosion-resistant waterborne txheej, nws kuj yog cov khoom nyiam.Yuav ua tau raws li qhov siab tshaj plaws kho qhov muag thiab rheological zog yuav tsum tau.HD605 series yog cov khoom lag luam tus qauv uas twb muaj lawm yam tsis muaj ethoxyalkyl phenol rau ob qho tib si hnyav hom thiab cov mis mos dej.Nyob rau hauv UV system, HD605 yog haum rau tag nrho cov pigments thiab cov khoom tsis muaj acetoxyalkyl phenol.
